About James
James Daloisio earned his J.D. from Whittier Law School in 1989. He entered the legal profession at a moment when tax law was evolving rapidly, and he has spent his career working in matters that touch both individual taxpayers and small businesses.
After graduating in 1989, Daloisio concentrated his practice on federal and state tax issues. He is admitted to practice in California and before the District Court for the Central District of California. He also maintains admission to the U.S. Tax Court, which shapes much of his litigation work. Those credentials have allowed him to represent clients in administrative proceedings and in court when disputes escalate.
His work ranges across income tax services, tax controversy, and representation in federal and tax-court proceedings. He prepares and reviews tax filings, advises on tax reporting obligations, and represents taxpayers in audits and collection matters. When cases move to litigation, he has handled filings and appearances in both district court and tax court forums.
Colleagues describe him as precise in his approach to tax issues. He tends to favor clear paper trails and careful documentation. That practical, document-driven style often matters in disputes over deductions, assessments, and statutory interpretation. His courtroom experience informs the way he prepares cases for administrative hearings as well as formal litigation.
Daloisio has operated under the banner of James Daloisio Professional Income Tax Services. The firm offers direct services to individuals, small business owners, and professionals who require hands-on handling of income tax matters. The practice environment is typically one of close client contact, and he often works directly with taxpayers to assemble records and explain procedural steps.
Throughout his career he has balanced advisory work with adversarial matters. That balance means he spends part of his time on planning and compliance, and part on dispute resolution. He recognizes that many clients seek both straightforward filing help and, when necessary, representation before taxing authorities.
As of 2026 he continues to practice through James Daloisio Professional Income Tax Services, providing income tax services, dispute representation, and related counsel to individuals and businesses.
